Table 41: Scheduling Order When Multiple Saps Are Configured On A Port; Table 42: Scheduling Order For Queues Within An Sap - Alcatel-Lucent 7210 SAS-R6 OS Quality Of Service Manual

The SAP aggregate shaper determines the bandwidth given to all FCs or queues belonging to the
SAP. The CIR rate is set by system to the sum of the CIR rate of all queues that belong to the SAP.
The port egress rate determines the outgoing traffic rate at a given port.

scheduled before cir-level "7" queues and so on.) until
CIR of all the queues are met or available bandwidth is
exhausted.
